A diamond-coated tool (80) and a process for making it. The process includes a sintering step. In that step, the tool substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool includes a large grain substrate surface, and a high bond strength between the diamond coating and the substrate surface.

L'invention concerne un outil (80) avec un revêtement en diamant et un procédé pour le réaliser. Le procédé comporte une étape de frittage. Dans cette étape, le substrat de l'outil est fritté dans une atmosphère, pendant une durée et à une température favorisant une croissance exagérée des grains en surface, qui apporte une rugosité de surface fournissant des sites d'ancrage durant l'étapte suivante d'application d'un revêtement en diamant, qui est exécutée en utilisant une technique par dépôt par évaporation sous vide. L'outil avec un revêtement en diamant comporte une surface à grands grains et il est caractérisé par une forte adhésion entre le revêtement en diamant et la surface du substrat.
